Once you have completed the de-duping process for a project, you can continue to incrementally check, match and add to it via API calls.

By posting a chunk of data to the API (described in the match endpoint), Dedupe.io can compare it to your dataset and return one or more potential matches. In the case where more than one result is returned, you can optionally tell Dedupe.io which one is correct and it will update the training for your dataset based on it (described in the train endpoint).
